What is Mini Keto Key Lime Cheesecake?
Mini Keto Key Lime Cheesecakes are a low-carb, sugar-free version of the classic key lime pie, presented in individual portions. Traditional key lime pie, while delicious, is typically high in sugar and carbs due to the graham cracker crust and sugary filling. In this keto-friendly version, we use almond flour for the crust and a sugar substitute for the sweetness, making these cheesecakes a perfect choice for anyone following a keto or low-carb diet.
These cheesecakes take inspiration from Florida’s famous key lime pie, known for its bright and tangy lime flavor. By using simple, keto-friendly ingredients, you can enjoy all the flavors of key lime pie without the guilt. Plus, these mini cheesecakes are easy to make and portion out, perfect for satisfying your sweet tooth without overindulging.

Low-Carb Key Lime Cheesecake Ingredients
Before you start baking, gather the following ingredients. Each plays an important role in creating the perfect keto cheesecake:
- Almond flour – This low-carb alternative to wheat flour forms the base of the crust. It provides a slight nutty flavor and a buttery, crumbly texture.
- Granular sweetener – A keto-friendly sugar substitute like erythritol or monk fruit is used to sweeten both the crust and the filling.
- Butter – Adds richness to the crust and helps bind the almond flour and sweetener together.
- Cream cheese – This is the base of the cheesecake filling, providing that classic creamy texture.
- Egg – The egg helps bind the filling and ensures it sets properly when baked.
- Sour cream – Adds tanginess and a bit of moisture to the cheesecake, balancing out the sweetness.
- Lime juice – The star of the show, lime juice gives the cheesecake its signature tart and zesty flavor.
- Cinnamon – A pinch of cinnamon in the crust adds warmth and depth to the flavor, contrasting nicely with the lime.
- Lime zest – Enhances the lime flavor and adds a beautiful pop of color.
For garnish:
- Whipped cream – Light and airy, it’s the perfect topping for these mini cheesecakes.
- Key lime slices – These add a decorative, fresh citrus touch to each cheesecake.
How to Make Mini Keto Key Lime Cheesecakes

Even if you’ve never made a cheesecake before, these mini keto cheesecakes are simple to prepare. Follow these steps carefully, and you’ll have a perfect batch of creamy, tangy cheesecakes every time.
- Preheat the oven – Start by preheating your oven to 350°F (175°C). Grease a 12-cup muffin tin and line each cup with muffin liners.
- Make the crust – In a bowl, mix the almond flour, two tablespoons of granular sweetener, and melted butter. Stir until the mixture forms a crumbly dough. Divide this dough evenly among the muffin cups, pressing it down firmly with the back of a spoon to create an even crust layer in each cup.
- Prepare the filling – In a separate bowl, beat together the cream cheese, remaining sweetener, egg, sour cream, and lime juice using a hand mixer. Mix until smooth and creamy, making sure there are no lumps. Stir in the lime zest to enhance the citrus flavor.
- Assemble the cheesecakes – Spoon about two tablespoons of the cream cheese filling into each muffin cup, on top of the crust. Smooth the tops with the back of a spoon.

- Bake – Place the muffin tin in the preheated oven and bake the cheesecakes for 15-20 minutes. The edges should be set, but the centers may still be slightly jiggly.
- Cool and chill – Remove the cheesecakes from the oven and allow them to cool in the muffin tin for about 20 minutes. Once they are cool, transfer the tin to the refrigerator and chill the cheesecakes for at least 1-2 hours. This helps the cheesecakes firm up and develop their full flavor.
- Garnish and serve – Once the cheesecakes have chilled, top them with whipped cream and a slice of fresh key lime. Enjoy your tangy, creamy dessert!

Tips for Making No Sugar Cheesecake
- Use room temperature ingredients – Make sure your cream cheese and sour cream are at room temperature to prevent lumps in the filling.
- Don’t skip the chilling time – Chilling the cheesecakes allows them to firm up properly, so don’t rush this step.
- Adjust sweetness to taste – Depending on your sweetener, you may want to adjust the amount to suit your taste. Some sweeteners are sweeter than others.
- Watch the baking time – Keep an eye on the cheesecakes while they’re baking. The edges should be set, but the centers can still jiggle slightly; they’ll firm up as they cool.
- Use fresh lime juice – Freshly squeezed lime juice and zest provide the best flavor. Avoid bottled lime juice if possible.
